Multi-screen man-machine interaction control device for medical X ray machine

Abstract

A multi-screen man-machine interaction control device for medical X ray machine belongs to the technical field of medical instruments. The device comprises a singlechip, a serial port conversion circuit, and a serial port liquid crystal touch screen. The device is characterized in that one control circuit board can simultaneously control a plurality of man-machine interaction screens, that is to say, can display the same man-machine interaction information, or display different man-machine interaction information under coordination of the singlechip. The invention has the advantages of general chip used in the device, low cost, powerful function, international general serial interface standard management, little wiring and safe and reliable running of the device.

Description

technical field [0001] The invention belongs to the technical field of medical equipment. Background technique [0002] At present, in the X-ray machine equipment in the electronic medical field, there are mainly two ways to realize the data information display of the X-ray machine, one is to use LED digital tubes, and the other is to use LCD screens. The LED digital tube can only display numbers and simple letters, the content is not rich, and the hardware occupies relatively more I / O resources of the single-chip microcomputer. Increased X-ray machine equipment. Using LCD screen as data display is gradually replacing the application of LED digital tubes in X-ray machines. At present, the most used method is to display data information through the control of single-chip microcomputer in parallel port mode.

Using LCD screen as data display is gradually replacing the application of LED digital tubes in X-ray machines. At present, the most used method is to display data information through the control of single-chip microcomputer in parallel port mode. When designing, the single-chip microcomputer requires the operation of parallel port LCD. Many I / O resources such as data lines and address lines can achieve the ultimate goal in effect, but the disadvantages are that they occupy relatively more I / O resources of the single-chip microcomputer on the hardware, and take up a lot of system time during control, which affects System control real-time

[0003] At present, there are mainly two ways of man-machine interactive operation control of X-ray machine, one is to use independent buttons, so that the independent buttons are arranged in the circuit board and managed by single-chip microcomputer. In this scheme, the I / O O There are a lot of resources. Due to the relatively large size of the independent buttons, the size of the final circuit board is also very large, which is not conducive to installation.

The second is to use integrated membrane keys. This solution can make a part of the keyboard scanning circuit inside the membrane keys, and the size of the circuit board will be considerably reduced. The single-chip microcomputer manages the keys through the interface with the membrane keys. This solution is similar to Compared with independent buttons, the I / O resources of some single-chip microcomputers are reduced, but they still occupy a considerable amount of I / O resources. At the same time, only simple graphics can be made to indicate user operations, which is not humanized enough.
